Facebook today announced the introduction of its mobile platform. The purpose of the project is to provide a social environment for mobile devices that will eventually mirror the company’s dominant Web-based platform. The initial mobile platform involves a number of projects across a variety of mobile operating systems — including iOS, Android and BlackBerry — and it will allow developers to more easily expand their Facebook products beyond the desktop environment.

On one end of the mobile spectrum, you have smartphone OSes that are feature packed, diverse and almost endlessly enhanceable. On the other end of the spectrum, you have dumb phone OSes that are limited in function but typically well-suited for the average consumer. Somewhere in the middle lies Qualcomm’s BREW Mobile Platform. Some may have been under the impression that BREW was going the way of the dinosaur but the truth is that it’s still managing to garner attention from manufacturers and carriers alike. Back in July, HTC reportedly let it be known that it has plans to release a BREW-powered handset some time in 2009. Now Sprint has jumped on board with this morning’s announcement that “it is planning to offer its customers additional device options by launching devices running Qualcomm’s Brew Mobile Platform™ (Brew MP).” No word yet on who might manufacture said phones, though HTC could certainly be among the companies currently working on a BREW-based Sprint handset. Whether or not the addition of BREW MP will be welcomed by Sprint subscribers remains to be seen but more options are never a bad thing, we suppose.
